Use a contactor when:
On 115V installations pump motor full load amps exceed 16 FLA.
On 230V installations pump motor full load amps exceed 20 FLA.
On all three-phase applications.
Remember, match coil voltage on contactor with BEST CONTROL voltage.
Either 115V or 230V coils may be used.
Use of magnetic starter to avoid damage to the device is determined by pump motor.
